    Small Diameter Machining High Feed Tool

  • Stable machining, high efficiency milling tools For small diameter machining.
Code System
Code System
Features
  • Apply helix cutting edge on insert, low cutting load and reinforce toughness on corner
  • Increased rigidity with double relief angle (11, 13), prevent interference with high feed
  • To apply the negative axial rake angle when set up the holder, increased chipping resistance
  • Tool life is increased with suitable C/B and grade for every material
